It
all starts with interstellar dust and cloud
Collapsing
under it’s own gravity to form
the
core heating upto several million degrees
starting
the fusion reaction, hydrogen atoms fusing
into
helium releasing enormous energy, a star is born!
Star,
the nature’s fusion reactor begins operations!
Spewing
enormous energy, photons, solar winds,
Neutrinos
all around the dazzling ball of light
The
interstellar dust and clouds didn’t turn into
A
star overnight, it took millions of years to do so
It
all don’t stop at hydrogen fusion into helium
Only
small stars stop at that level Stars more than
1.5
solar masses to 3 solar masses, more than
3
solar masses all continue fusion by Helium ,carbon
neon, oxygen,magnesium, silicon fusions
The
fusion goes right upto iron core where it takes
More
energy in reaction than to give out
Resulting
in inward collapse and massive heating
and
supernova explosion expelling dust and cloud
From
dust & cloud stars form anew starting all over again!
Stars
born, dazzle in fusion billions of years
exhaust
all fusion stuff end up white dwarf, neutron stars,
black
holes depending on the mass and size
of
the stars after supernova explosion,expelling
dust
and cloud to form star the nature’s fusion reactor!
